Abnormal particle heating in the plasma dust structures

Physical electronics

In order to explain the nature of abnormal particle heating in the plasma dust structures (PDS) based on helium-group gases, kinetic characteristics of PDS have been studied experimentally and theoretically. To inject the dust component, a container with particles of dispersed materials of different nature was used. The visualization and monitoring of PDS behavior as well as measuring of plasma parameters were carried out via specially designed hardware and software complex. The rates and temperatures of dust particles depending on the discharge conditions were determined experimentally. An analysis of the obtained results made it possible to reveal the process peculiarities and to put forward the explanation of mechanism of heating and dissipation of particle energy in the ordered and chaotic PDSs.
